+
+This is a CVEX based Lens Shader used to generate Impostors inside the Impostor Texture ROP. This tool by itself is exposed because of its educational worth.
+Please note that the lens shader code is found in the "Code" section of the HDA.
+
+@parameters
+    xy_size:
+	This specifies the number of impostor renders there are generated for both X and Y axis. (Ex 8 would result in 64 angles)
+    camera_width:
+	Sets the camera width of the lens shader. A larger camera width allows for larger objects to be rendered.
+    camera_zoom:
+	Controls the zoom of the lens. Smaller values means more zoomed in.
+    imposter_mode:
+	Sets the type of octahedral impostor that needs to be rendered.
